Matter Creation

Matter creation is the process inverse to particle annihilation. It is the conversion of massless particles into one or more massive particles. This process is the time reversal of annihilation. Since all known massless particles are bosons and the most familiar massive particles are fermions, usually what is considered is the process which converts two bosons (e.g. photons) into two fermions (e.g., an electron–positron pair).

Famous quotes containing the words matter and/or creation:

    It is the spirit of the age to believe that any fact, no matter how suspect, is superior to any imaginative exercise, no matter how true.
    Gore Vidal (b. 1925)

    The creation of “strong-minded” women, so-called, is due to the individualism of men, to the modern selfish and speculative spirit which absorbs everything within itself and leaves women nothing but self-assertion for their protection and support.
